Unrolled and Pipelined Decoders based on Look-Up Tables for Polar Codes
Pascal Giard, Syed Aizaz Ali Shah, Alexios Balatsoukas-Stimming +2
Unrolling a decoding algorithm allows to achieve extremely high throughput at the cost of increased area. Look-up tables (LUTs) can be used to replace functions otherwise implement…
Trainable Communication Systems: Concepts and Prototype
Sebastian Cammerer, Fayçal Ait Aoudia, Sebastian Dörner +3
We consider a trainable point-to-point communication system, where both transmitter and receiver are implemented as neural networks (NNs), and demonstrate that training on the bit-…
Joint Learning of Geometric and Probabilistic Constellation Shaping
Maximilian Stark, Fayçal Ait Aoudia, Jakob Hoydis
The choice of constellations largely affects the performance of communication systems. When designing constellations, both the locations and probability of occurrence of the points…
Decoding of Non-Binary LDPC Codes Using the Information Bottleneck Method
Maximilian Stark, Jan Lewandowsky, Souradip Saha +1
Recently, a novel lookup table based decoding method for binary low-density parity-check codes has attracted considerable attention. In this approach, mutual-information maximizing…
